Two high school students, Sum Ming Wong and Kin Pong Li, both living in Hong Kong have designed and built a door handle that kills germs, thus preventing the spread of disease through hand contact. They demonstrated their handle at the Intel International Science and Engineering Fair held last month in Pittsburgh—taking second place in the materials science category.
